Introduction to Kidney Function Tests
A kidney function test checks how well your kidneys are working. These tests help doctors find out if your kidneys are healthy or if there are problems. Often, a kidney function test uses blood or urine samples. Because kidneys play a key role in removing waste, checking their health is important for your overall well-being.
Why Are Kidney Function Tests Important?
Kidneys filter waste and extra water from your blood. They also help control blood pressure and balance minerals. If your kidneys do not work well, waste can build up in your body. Therefore, a kidney function test can spot problems early. Early detection allows for better treatment and can prevent serious health issues.
